<p>The present invention relates to an apparatus to automatically detect a starting point of a welding robot torch which sets up a supporter on a base, installs a torch detecting sensor and a limit switch on the supporter, installs a starting point detecting part whereby a starting point becomes on when pressed by a welding wire of a torch on the base, and can automatically detect a starting point return state of a torch and display a state constituted to output on a monitor by judging as normal when the starting point detecting part detects the starting point, but judging as a starting point return error when the starting point detection fails after a starting point control part detects a starting point return of the torch of the torch detecting sensor.</p> |
